Method and system for purifying nitrogen trifluoride containing halogen or halogen compound as impurity |
| abstract |
A method for purifying nitrogen trifluoride containing a halogen or a halogen compound as an impurity, which comprises a step wherein the nitrogen trifluoride is brought into contact with water, a step wherein the nitrogen trifluoride is brought into contact with an aqueous base solution, and a step wherein the nitrogen trifluoride is brought into contact with an aqueous solution of a reducing agent. By this method, impurities can be removed while suppressing production of halogen oxides, and nitrogen trifluoride can be purified with high purity at low cost. |
